Abstract
The utility model relates to a rear -mounted steam pipe oven's burner structure at the competent burning zone furnace of the vertical section of going upward furnace's lower end connection, at the competent mixing section furnace of the vertical section of going upward furnace's last end connection, has gas burner at horizontal firing section furnace's other end externally mounted, is equipped with the gas cooler in the vertical section of going upward furnace, is equipped with the thermoscope and restraints with end connection 1 in horizontal mixing section furnace. The utility model discloses a high temperature flue gas that burner produced is passed through to the form of arranging of rear -mounted combustor, coal gas, moves ahead along furnace, and it goes upward to turn again, turns to erode superheater tube and restraint again, goes upward the district and arranges the heat sink, and high temperature flue gas and cooling gas make superheater tube restraint each position and are heated evenly in the cooling of mixed zone intensive mixing, avoids the boiler tube burning to burst, furnace adopts the C type form of arranging, the dwell time of extension fuel in furnace, and what do benefit to fuel fully fires the cinder.
Description
Technical field
This utility model is related to a kind of burner structure of steam pipe oven, and this utility model is rearmounted more particularly, to one kind
The burner structure of formula steam pipe oven.
Background technology
Steel plant are in the technical processs such as steel-making, steel rolling as converter, a large amount of low temperature of heating furnace apparatus for vapour-cooling generation are low
Pressure saturated vapor, in addition to a small amount of using by oneself, most of low-pressure saturated steam often cannot be utilized rationally, idle discharge can only be put, both
Environment is polluted, the significant wastage of the energy is caused again.
The arrangement form of steam pipe oven burner is varied in steel industry, there is through type, i.e. burner arrangement
In front of superheater surface；Also have before heating surface and arrange a vertical shaft, burner arrangement is in silo bottom.Or because of live place
Limit, it is impossible to meet coal gas and burn required enough stroke distances, most of high-temperature flue gas directly wash away superheater surface,
Even if heat sink is provided with before heating surface, but because apart from limited, everywhere flue-gas temperature cannot be effective for superheater surface
Control, cause superheater front row boiler tube burning, pipe explosion accident to take place frequently.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of combustion for effectively improving coal gas
The burner structure of cinder rate, the rear-mounted steam pipe oven of the booster frequency of reduction superheater.
According to the technical scheme that this utility model is provided, the burner structure of the rear-mounted steam pipe oven, including coal
Air burner, horizontal firing section burner hearth, vertically up section of burner hearth, horizontal mixing section burner hearth, gas cooler, thermal detector with it is overheated
Device is restrained；Horizontal firing section burner hearth is connected with the bottom of vertical up section of burner hearth, in the upper end of vertical up section of burner hearth
Horizontal mixing section burner hearth is connected with, gas burner is installed outside the other end of horizontal firing section burner hearth, vertically up
Gas cooler is provided with section burner hearth, in horizontal mixing section burner hearth thermal detector and superheater bank, thermal detector and flue gas are provided with
Cooler is connected by holding wire, and superheater bank is arranged on the front of thermal detector.
The length direction of the horizontal firing section burner hearth is vertical setting with the length direction of vertical up section of burner hearth, vertically
The length direction of up section of burner hearth is vertical setting with the length direction of horizontal mixing section burner hearth.
The gas cooler is arranged on the medium position in vertical up section of furnace height direction.
This utility model has advantages below：
1st, using the arrangement form of rear-mounted burner, using the lower space of superheater surface, by gas burner
Superheater lower space is arranged in, steam superheater compact conformation, floor space is few；
2nd, the high-temperature flue gas produced by burner combustion using the arrangement form of rear-mounted burner, coal gas, along stove
Thorax moves ahead, then turns up, then turns and washes away superheater bank, and up area arranges heat sink, high-temperature flue gas and cooling gas
Cooling is sufficiently mixed in mixed zone, each position of superheater bank is heated evenly, it is to avoid boiler tube burning bursts；
3rd, burner hearth adopts c-type arrangement form, extends the time of staying of the fuel in burner hearth, fully burning beneficial to fuel.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
With reference to specific embodiment, the utility model is described in further detail.
The burner structure of the rear-mounted steam pipe oven, including gas burner 1, horizontal firing section burner hearth 2.1, vertically
Up section of burner hearth 2.2, horizontal mixing section burner hearth 2.3, gas cooler 3, thermal detector 4 and superheater bank 5；At vertically up section
The bottom of burner hearth 2.2 is connected with horizontal firing section burner hearth 2.1, and in the upper end of vertical up section of burner hearth 2.2 level is connected with
Mixing section burner hearth 2.3 so that by horizontal firing section burner hearth 2.1, vertically up section of burner hearth 2.2 and the horizontal structure of mixing section burner hearth 2.3
Into burner hearth be in " C " font, gas burner 1 is installed outside the other end of horizontal firing section burner hearth 2.1, vertically up
Gas cooler 3 is provided with section burner hearth 2.2, thermal detector 4 and superheater bank 5, thermometric are provided with horizontal mixing section burner hearth 2.3
Device 4 is connected with gas cooler 3 by holding wire, and superheater bank 5 is arranged on the front of thermal detector 4.
The length direction of the horizontal firing section burner hearth 2.1 is perpendicular with the length direction of vertical up section of burner hearth 2.2 to be set
Put, vertically the length direction of up section of burner hearth 2.2 is vertical setting with the length direction of horizontal mixing section burner hearth 2.3.
The gas cooler 3 is arranged on the medium position of the vertical up section of short transverse of burner hearth 2.2.
The high-temperature flue gas that coal gas is produced by the burning of gas burner 1, move ahead along horizontal firing section burner hearth 2.1, then turn
Curved rising, enters vertical up section of burner hearth 2.23, is vertically disposed with gas cooler 3 in up section of burner hearth 2.2, and high-temperature flue gas exist
The cooling gas that vertically up section of burner hearth 2.2 is sprayed into gas cooler 3 are contacted, and the horizontal mixing section burner hearths 2.3 of Jing are sufficiently mixed.
The cigarette temperature measured according to the thermal detector 4 before superheater surface is controlling the amount that gas cooler 3 sprays into cooling gas.Flue gas
Temperature is controlled effectively, then washes away superheater bank 5, and each position of superheater bank 5 is heated evenly, it is to avoid boiler tube burning,
Cause booster.
